The ZCZG series high-temperature high-pressure solenoid valve is an automated execution unit specifically designed for demanding industrial environments, primarily used for the automatic on/off control of steam, hot water, thermal oil, and other high-pressure media. Utilizing an advanced pilot-operated piston structure, it consists of a heat-resistant electromagnetic coil and a high-strength metal body. The core design features a metal-to-metal hard seal or specialized temperature-resistant synthetic materials, ensuring superior sealing performance under extreme thermal and pressure cycles. By converting electrical signals into electromagnetic force to open the pilot hole, it utilizes the media's own pressure differential to actuate the main piston. The ZCZG series is widely used in power plants, petrochemicals, and thermal energy systems due to its robust temperature resistance and rapid actuation.Product Image of ZCZG High-Temperature and High-Pressure Solenoid Valve

The GWDRY Series Pilot Operated Piston High-Temperature Solenoid Valve (with nominal sizes spanning from DN15 to DN50) is a premium, heavy-duty automatic control valve engineered for modern industrial thermal networks, high-temperature gas transmission lines, complex liquid circulation loops, and high-severity thermal oil (heat transfer fluid) automation networks. Serving as a crucial isolation component within automated fluid loops, this series features advanced structural optimization designed to solve common industry issues such as carbon choking, mechanical jamming, and thermal deformation leaks. This series offers both threaded and flanged connection profiles, with models featuring suffixes "F" and "JF" custom-tailored for medium-to-high pressure industrial flanged pipelines. The GWDRY series operates as a Normally Closed (NC) valve utilizing a fluid-assisted pilot-operated mechanism.When the electromagnetic coil is de-energized, the internal plunger is forced downward by the return spring, completely sealing the central pilot orifice located at the geometric center of the main piston. Consequently, the upstream process fluid flows from the inlet side into the upper piston cavity via a specialized balancing throttling port. Because the pilot orifice is sealed, fluid pressure rapidly builds within the upper chamber until it reaches static equilibrium with the inlet line pressure. Leveraging the design geometry where the upper surface area of the piston is larger than the lower surface area, a downward net pressure differential is established. This high net fluid force, combined with the mechanical pre-load of the main return spring, presses the piston assembly firmly against the body seat, ensuring a zero-leakage tight shutoff. When the electromagnetic coil receives an electrical current, it generates a high-density magnetic field. The resulting electromagnetic force overcomes the combination of internal spring resistance and plunger weight, pulling the plunger upward to open the central pilot orifice instantly. Because the cross-sectional flow area of the pilot orifice is significantly larger than that of the lateral balancing throttling port, the high-pressure fluid trapped in the upper piston chamber evacuates rapidly toward the low-pressure downstream side of the valve. This creates an immediate drop in upper chamber pressure. Consequently, the upstream process fluid pressure acting on the lower surface of the piston overcomes the residual upper chamber pressure, creating a strong upward net thrust. This force compresses the main spring and lifts the heavy piston assembly smoothly along the guided walls of the valve cavity, opening the valve completely. When the power is disconnected, the upper chamber pressure re-establishes within milliseconds, driving the piston down to complete the isolation cycle.Product Image:GWDRY Piston Type High-Temperature Solenoid Valve

The YSE Series Direct Acting Stainless Steel High Pressure Solenoid Valve (with nominal orifice sizes spanning from DN1 to DN5, equivalent to 1mm to 5mm internal sizing) is an ultra-high-pressure automatic control valve engineered for high-pressure gas distribution networks, high-pressure hydraulic control systems, high-pressure washing machinery, aerospace ground test manifolds, and automated pipelines transporting light low-viscosity oils (viscosity less than or equal to 20 cst). Serving as a critical final execution element within high-pressure circuits, this series features advanced structural hardening specifically optimized to solve industry vulnerabilities under 300 bar (30 MPa) ultra-high static pressures, such as external packing leakage, valve needle deformation, and electromagnetic actuation failure caused by excessive high-pressure resistance. All models feature a premium SS304 stainless steel body with high-integrity G or NPT threaded connection profiles. The YSE series operates as a Normally Closed (NC) valve utilizing a true direct-acting electromagnetic configuration.Unlike pilot-operated valves that require a minimum working pressure differential between the upstream and downstream pipelines to stroke the valve, the direct-acting mechanism operates completely independently of system pressures. Even under zero differential pressure (0 bar), the valve guarantees precise, millisecond-level actuation. When the electromagnetic coil is de-energized, the heavy-duty internal plunger is driven downward by a high-tension compressed return spring, pushing a high-hardness stainless steel valve needle (or custom ultra-high pressure composite disc) directly onto the micro-orifice seat. At this stage, even when subjected to an upstream static pressure of 300 bar, the valve uses direct mechanical force and micro-engineered hard-seating boundaries to block the process medium, achieving a tight shutoff. When the electromagnetic coil receives an electrical current, a high-power, custom-wound solenoid coil instantly generates a high-density magnetic field. This electromagnetic force directly overcomes the resistance of the high-tension return spring, the weight of the plunger assembly, and the heavy high-pressure holding force exerted by the 300 bar medium on the valve needle face. The plunger is pulled upward in a crisp, linear motion, lifting the valve needle off the micro-seat. Because the electrical force acts directly upon the sealing needle without secondary pilot chambers, the micro-orifice opens completely, allowing full fluid transmission. When power is disconnected, the magnetic field collapses within milliseconds, and the high-tension spring forces the needle back down to complete the high-pressure isolation cycle.Product Image:YSE Direct Acting Stainless Steel High Pressure Solenoid Valve

Высокопрочный электромагнитный клапан высокого давления из нержавеющей стали пилотного типа серии YSE (номинальный диаметр охватывает диапазон от DN6 до DN25) представляет собой высокотехнологичное оборудование для управления потоками жидкостей и газов при среднем и высоком давлении и больших расходах. Он специально разработан для автоматизированных трубопроводов транспортировки газов высокого давления, гидравлических систем управления, оборудования для мойки высокого давления, а также для различных видов легких масел с низкой вязкостью (вязкость менее или равна 20 сСт). Будучи ключевым исполнительным элементом в контурах автоматического управления высокого давления, данная серия прошла глубокую структурную оптимизацию с учетом таких критических проблем отрасли, как отказ в срабатывании из-за недостаточного электромагнитного усилия при высоком статическом давлении до 160 бар (16 МПа) на больших диаметрах, а также эрозия уплотнений, вызванная чрезмерно высокой скоростью потока. Вся серия в стандартной комплектации оснащается высококачественным корпусом из нержавеющей стали SS304 и предлагает два типа высоконадежных резьбовых соединений: трубную резьбу G и коническую резьбу NPT. Клапаны данной серии используют пилотный механизм управления и относятся к типу нормально закрытой автоматической арматуры. В отличие от клапанов прямого действия, где электромагнитное усилие напрямую поднимает шток, ключевое преимущество пилотного клапана заключается в том, что он эффективно использует давление самой рабочей среды для перемещения главного затвора. Когда электромагнитная катушка обесточена, пилотное отверстие закрыто под действием усилия возвратной пружины, и рабочая среда через перепускной канал поступает в полость над главным поршнем. Это создает сбалансированное распределение давления между верхней и нижней частями поршня (или с преобладанием давления сверху). Под совместным воздействием силы главной пружины и давления среды главный поршень плотно прижимается к главному седлу, обеспечивая абсолютно надежное перекрытие потока с нулевой утечкой. При подаче питания на электромагнитную катушку создается магнитное поле, которое сначала открывает пилотное отверстие. В этот момент рабочая среда из полости над главным поршнем быстро сбрасывается через пилотное отверстие. Поскольку нижняя сторона поршня по-прежнему находится под воздействием высокого давления со стороны входа, между верхней и нижней сторонами главного поршня мгновенно возникает значительный перепад давлений. Направленная вверх сила, вызванная этим перепадом давлений, напрямую преодолевает сопротивление главной пружины и собственный вес поршня, стремительно поднимая главный поршень вверх. Главное проходное отверстие мгновенно полностью открывается, восстанавливая беспрепятственный поток среды с большим расходом. Как только катушка обесточивается, пилотное отверстие закрывается за доли миллисекунды, давление над главным поршнем снова возрастает, заставляя его на высокой скорости опускаться в исходное положение для запирания, завершая быстрый и жесткий цикл отсечки.Изображение изделия:Двухходовой двухпозиционный высоковольтный электромагнитный клапан YSE из нержавеющей стали с пилотным управлением

The YSE-A series pilot-operated stainless steel ultra-high pressure solenoid valve (nominal diameter ranging from DN10 to DN25) is a high-end, ultra-high pressure fluid control device specially developed for ultra-high pressure, large-flow fluid transmission and extremely severe operating conditions. As a core shut-off element in ultra-high pressure automated pipeline systems, this series features deep structural optimization targeting common industry pain points under 700bar (70MPa) ultra-high static pressure and large-bore working conditions, such as the inability to open under low pressure differentials, valve core deformation under high-pressure shocks, and seal erosion under large flow rates. The entire series comes standard with high-specification SS304 stainless steel bodies and offers two highly reliable interface types: G thread and NPT thread. It is widely used in high-pressure hydrogen storage and transportation, ultra-high pressure hydraulic pump stations, aerospace ground testing, and high-end industrial cleaning systems. This series of valves utilizes a pilot-operated control mechanism and belongs to the normally closed automatic valve type. Its core advantage lies in the innovative zero-differential pilot drive structure, which perfectly combines the rigid control of electromagnetic force with the fluid dynamics of the medium's own pressure differential. When the electromagnetic coil is de-energized, the pilot valve port remains closed under the action of the return spring force. The medium enters the cavity above the main piston through the fluid channel, forming a balanced or top-high-bottom-low pressure distribution across the upper and lower ends of the piston. Under the combined sealing action of the main spring force and the 700bar ultra-high medium pressure, the main piston is tightly pressed against the main valve seat, achieving absolutely reliable, zero-leakage high-pressure shut-off. When the electromagnetic coil is energized, a specially customized high-power, super-magnetic coil instantly generates a powerful electromagnetic attraction force that first pulls open the pilot valve port. Thanks to its special forced-lift mechanism, even in an extreme zero-pressure state where the system pressure differential is 0bar, the electromagnet can directly lift the main piston mechanically via a linkage, ensuring 100% precise actuation. When a pressure differential exists in the system, the medium in the cavity above the main piston quickly relieves pressure to the outlet end through the pilot hole, utilizing the huge pressure differential thrust of the fluid to push the main piston to the fully open position, restoring highly efficient, large-flow passage. Once the coil is de-energized, the electromagnetic field disappears, and the pilot hole and main piston reset downward at high speed within milliseconds, completing a rapid and rigid high-pressure cut-off cycle.Product Image:YSE-A 2/2-Way Normally Closed Ultra-High Pressure Solenoid Valve

The YSI series pilot piston-type stainless steel high-pressure solenoid valve (nominal diameter ranging from DN15 to DN50) is a high-end automated control device specially developed for medium-to-high pressure and large-flow fluid transmission pipelines. As a core executive element in large-bore high-pressure pipeline systems, this series features deep structural optimization targeting common industry pain points under 100bar (10MPa) high static pressure and large-bore working conditions, such as external packing leakage, main seal tearing and destruction caused by large-flow high-velocity scouring, and valve failure to actuate due to insufficient electromagnetic force. The entire series comes standard with high-specification SS304 stainless steel bodies, utilizes a heavy-duty piston guiding structure, and offers two highly reliable interface types: G thread and NPT thread. It is widely used in large high-pressure cleaning pump stations, centralized gas supply networks, hydraulic stations, and various industrial automated large-flow fluid control loops. This series of valves utilizes a pilot piston-type control mechanism and belongs to the normally closed automatic valve type. Its core advantage lies in the ingenious utilization of the medium's own pressure differential fluid dynamics to drive the large-bore main piston. When the electromagnetic coil is de-energized, the pilot hole remains closed under the action of the return spring force. The medium enters the cavity above the main piston through the fluid channel, forming a balanced or top-high-bottom-low pressure distribution across the upper and lower ends of the piston. Under the combined sealing action of the main spring force and the 100bar medium pressure, the large-bore stainless steel piston is tightly pressed against the main valve seat, achieving absolutely reliable, zero-leakage shut-off. When the electromagnetic coil is energized, a customized high-power coil instantly generates a strong electromagnetic attraction force that first opens the pilot hole. At this moment, the medium in the cavity above the main piston quickly relieves pressure to the outlet end through the pilot hole. Since the lower side of the piston still bears the high pressure from the inlet end, a huge pressure differential is instantly formed between the upper and lower sides of the main piston. The upward thrust generated by this pressure differential directly overcomes the main spring resistance and the piston's dead weight, rapidly pushing the large-bore main piston upward. The main valve port is instantly fully opened, and the medium restores large-flow, unhindered passage. Once the coil is de-energized, the electromagnetic field disappears, the pilot hole closes at high speed, and pressure rebuilds above the main piston, driving the piston downward rapidly to reset and lock, completing a rapid and rigid cut-off cycle.Product Image:YSI 2/2-Way Piston Type High Pressure Solenoid Valve

The YSP series pilot piston-type stainless steel high-pressure solenoid valve (nominal diameter ranging from DN15 to DN50) is a high-end fluid control device specially designed and developed for medium-to-high pressure and large-flow fluid automated pipeline control. As a core control executive element in large-bore industrial pipeline loops, this series features deep structural optimization targeting 50bar (5MPa) working pressure and large-bore working conditions. It focuses on solving common industry pain points under high-frequency switching, such as main seal erosion and wear, valve core jamming, and the tendency of traditional diaphragm structures to tear and fail under high pressure.

It is widely used in medium-to-high pressure cleaning equipment, factory centralized gas supply systems, water treatment networks, hydraulic control base machines, and various gas and liquid automated control engineering. This series of valves utilizes a pilot piston-type control mechanism and belongs to the normally closed automatic valve type. Its core advantage lies in the ingenious utilization of the medium's own pressure differential fluid dynamics to drive the large-bore main piston, thereby greatly reducing the power consumption of the electromagnetic coil. When the electromagnetic coil is de-energized, the pilot hole remains closed under the action of the return spring force. The medium enters the cavity above the main piston through the fluid channel, forming a balanced or top-high-bottom-low pressure distribution across the upper and lower ends of the piston. Under the combined sealing action of the main spring force and the medium system pressure, the piston assembly is tightly pressed against the main valve seat, achieving absolutely reliable, zero-leakage shut-off. When the electromagnetic coil is energized, the customized coil instantly generates a strong electromagnetic attraction force that first opens the pilot hole. At this moment, the medium in the cavity above the main piston quickly relieves pressure to the outlet end through the pilot hole. Since the inlet end of the pipeline bears a system pressure of no less than 0.5bar, a distinct pressure differential is instantly formed between the upper and lower sides of the main piston. The upward thrust generated by this pressure differential directly overcomes the main spring resistance and the piston's dead weight, rapidly pushing the main piston upward. The main valve port is instantly fully opened, and the medium restores large-flow, unhindered passage. Once the coil is de-energized, the electromagnetic field disappears, the pilot hole closes at high speed, and pressure rebuilds above the main piston, driving the piston downward rapidly to reset and lock, completing a rapid and rigid cut-off cycle.Product Image:YSP 2/2-Way Piston Type High Pressure Solenoid Valve
